INSTALLATION GUIDE Outback Clearspan Gable WITH COOLDEK ROOFING BEFORE YOU START It is important to check your Local Government Authority requirements before the installation of your new Stratco Outback Clearspan Gable. It is the builder s responsibility to ensure any existing structure that an Outback Clearspan Gable is being attached to is adequately reinforced to accommodate the additional loads imposed by the verandah, patio or carport. Read these instructions thoroughly before starting your project and refer to them constantly during each stage of construction. Contact Stratco for advice if you do not have the necessary tools or information. Before starting, lay out the main components in order of assembly on the ground and check them against the delivery note. The Components section identifies each part of your Outback Clearspan Gable with Cooldek and shows the relative location of the components. Mark out the overall area of your verandah, patio or carport and ensure that it is free from obstructions. Beam to wall connections can cause difficulty if they coincide with door and window openings, so avoid these in your design. Ensure there is reasonable access for materials and working space and consider the disposal of run-off water. Check the column and positions on the ground; roughly check they are square by measuring the diagonals, then mark out the column locations. If columns are to be in ground, dig the holes to Stratco specifications. ADDITIONAL MATERIALS The Outback kit does not include fixings to attach the unit to an existing structure or concrete/masonry anchors for the column installation. Other items not included in the standard kit are infill panels and accessories, box s and cover flashings. If required, they must be purchased as additional items.

COMPONENT LAYOUT angled back channel ridge gable frame cooldek header capping cutback flashing GABLE FRAME ASSEMBLY The first step when installing your Clearspan Ultimate with Cooldek is to assemble the gable frame. This will determine your gable opening which will be used when setting up the rest of the frame work. open gable rafter IMPORTANT: When assembling the gable frame ensure that the double thickness portion of the s is on top and the seam is on the same side. The rafters are supplied pre-cut and drilled at the ridge. There are two types of rafters used depending on whether a header is being installed, these are shown in Figure 1.0. Insert the ridge knuckle into the pre-cut rafters and screw together using two 12x20 hex head self drilling screws through both sides of each rafter and two 12x20 hex head self drilling screws through the top (double flange side) of each rafter (figure 1.1). Make sure that the two ends are flush at the connection, leaving no gaps. Measure the distance between rafter ends, O, to check spacing (Figure 1.2). This will become the gable opening dimension. infill gable rafter (header ) 12 X 20 hex head self drilling screws ridge knuckle Figure 1.0 12 X 20 hex head self drilling screws gable rafters gable opening (O) Figure 1.2 Figure 1.1
VALLEY BEAM ASSEMBLY Before erecting any s the capping needs to be fixed to the top of the s. The capping will support the Cooldek when it is laid and the gable s will be attached to the capping. When fixing the capping ensure that the double thickness of the is on top. Fix the channel to the top of the using 12x20 hex head self drilling screws at maximum 500mm centres and with two screws at the location of all rafters as shown in figure 2.0. Fix the capping to the channel using 3mm rivets or 12x 20 hex head screws each side at maximum 500mm centres and with two rivets either side of the location of all rafters. Ensure the break is located in the top groove (figure 2.0). locate the break on the capping in top groove of channel capping fix capping to channel using 3mm rivets each side at 500mm centres. Fix with two rivets either side at the location of a rafter. fix channel to top of valley using 12 x 20 hex head self drilling screws at 500mm centres. Fix channel with two screws at the location of a rafter. If attaching the to a header, notch the capping so that it sits on top of the header as shown in figure 6.6. Figure 2.0 ATTACHING ON SIDE TO HOUSE A Stratco Clearspan attached on its side to a house is attached to the existing eaves overhang at the fascia, or to an existing wall if height permits. The first objective in the construction is to fix a structural side along the fascia or wall, to which the Gable Unit is attached. Most existing houses have not been designed for the attachment of portal framed gables to their side, therefore additional strengthening of the house rafters must be performed. In order to strengthen the existing house rafters, the roof tiles or roof sheets need to be lifted to expose the roof frame. Steel rafter s and channels are then bolted along the house rafters. M12 bolt rafter strengthening 60x44x2.0 G450 galvanised channel An attachment is bolted to the strengthening s at the fascia. Once the attachment is secured to the house, the Gable Unit can be erected and fastened to the. The first step is to determine the number of rafters which need to be strengthened and their location relative to the unit. You will have to lift some roof tiles or roof sheets to discover the rafter positions and spacings. The number of rafters which need to be strengthened is determined by the builder, however spacing is recommended not to exceed 1200mm. timber rafter Figure 3.0 Note: It is the builder s responsibility to ensure the existing rafters and fascia are adequately reinforced and strengthened to accommodate any additional attached structure. The reinforcing method must be approved by the appropriate council or engineer. It is recommended an adjustable rafter strengthening is used in conjunction with an extension channel, as shown in figure 3.0. The adjustable rafter strengthening is shown in figure 3.1. Adjustable Rafter Strengthening Bracket Figure 3.1
RAFTER STRENGTHENING BRACKETS AND CHANNELS The adjustable rafter strengthening allows for an adjustment of pitch in the range of 15 to 30 degrees. The distance the extends past the fascia is also adjustable to allow for standard s or box s with a width of up to 200mm. In conjunction with rafter strengthening s a channel is fixed to the side of the house rafter (figure 3.0). The bottom end of the channel will be located at the base of the house rafter. Holes should be marked and pre-drilled in the channel to suit the location of existing holes in the. The channel will extend beyond the so additional holes are to be drilled in the channel at approximately 500mm centres. Initially the T piece shall be fixed to the arm with two M12 cup head bolts (hand tighten only), a spring washer is to be located between the standard M12 washer and nut (figure 4.0). Mark the position of the on the fascia and notch a rectangular hole in the fascia allowing the to be fed through the front of the fascia. The hole may need to be enlarged slightly if the M12 cup head bolts interfere with the fascia. Insert the through the fascia and fix with the channel to the house rafter using M12 hex head bolts through the existing holes in the and further up the channel (Figure 4.3). Adjust the T piece so it is horizontal and has the appropriate extension past the fascia to allow for fixing of the attachment. T piece connection bolts are to be tightened to a minimum 50Nm torque. Fix the as close to the base of the as possible (recommended distance 10mm from lowest end of ), as shown in figure 4.1. The attachment is to be fixed to the end plate to ensure the roof sheets drain into the existing house (figure 4.1). cooldek roof sheet arm t piece enough clearence for roof sheets to run into house guttet tighten to 50Nm torque M12 washer M12 spring washer rafter M12 cup head bolt M12 nut rafter strengthening attachment fix as close as possible to the base of the Figure 4.0 Figure 4.1 web overhang recommended channel extension beyond birds mouth: 1900mm recommended web overhang: 400mm channel extension timber rafter rafter strengthening attached to rafter with 6 M12 hex head bolts channel attachment fixed to rafter with two M12 bolts birds mouth stud wall rafter eaves overhang brick work attachment Figure 4.3
FIXING THE ATTACHMENT BEAM IN PLACE After fixing all the s and channels, the attachment can capping now be fixed into place. Prop the attachment in position with the capping on top, the will need to be located at a height on the which allows clearance between the Cooldek and the. Fix to the end plates of the rafter using two M12 bolts, with the bolt head on the attachment side. Insert spacers to prevent the from crushing, and bolt in position, using nuts and washers. To insert spacers drill 13mm holes through the attachment. Then drill 16mm holes on the outside face only, but this time do not drill all the way through. This will allow the spacer to slide in from the outside and stop at the other side as shown in figure 5. attachment rafter strengthening nut 13mm hole channel double flange spacer washer enlarged hole (16mm this side only) M12 bolt A cover flashing may be ordered as an additional option and custom made to cover the exposed s and holes through the fascia.

Figure 5.0 The attachment becomes the base for the attachment of the Clearspan Gable unit. house attachment Note: Do not over tighten bolts as this can lead to a visible indentation due to the high gloss nature of the material. Refer to figure 5.0 for fixing spacers. strengthening fascia rivet rivet cover flashing (optional) END ATTACHED UNITS Figure 5.1 If fixing a Clearspan Gable on its end to a wall, s are fixed directly to the wall using to wall s. The rear gable frame will need to be offset from the wall to allow the appropriate fixing. Wall s are positioned either side of the gable opening at the spacing determined in the section Gable Frame Assembly. The folded section on the tabs of the is located at the top (figure 6.0). The highest point of the wall will be 15mm below the top of the. Mark the holes and drill using an 8mm masonry bit. Fasten the to the wall with two M8 masonry anchors to a minimum 65mm embedment. Locate the first ( cap on top) up into the wall so the curved flange locate against the top flute of the. The is fastened to the wall with two 12x20 hex head screws either side in the pre-drilled holes while the opposite end is supported on adjustable construction props. If required, additional hold down to the wall may be obtained by using tie down s, refer figure 6.1. A suspension is used when a is suspended from the fascia (figure 6.3).

Use silicone to seal behind the suspension and fascia. For steel fascia a minimum of three M6 bolts with washers are fixed through the suspension and fascia. For timber, three 12x25 type 17 screws are used to fix through the suspension and timber. Refer figure 6.2 for fastener locations. The first is slid into position and fastened using three 12x20 self drilling screws either side (figure 6.3), while the opposite end is supported on adjustable construction prop. It is recommended extended fascia strengthening s and reinforcing channels are fastened at a spacing not exceeding 1200mm centres to fascia and rafters (figure 6.3). Brackets are also recommended to the first rafter either side of the s. Secure s and channels to rafters with 12x25mm timber fixing screws through pre-drilled holes and bolt through fascia with M10 bolts. If required, additional fascia reinforcement may be obtained by securing RHS tubing behind the fascia, refer figure 6.4. If fixing a Clearspan Gable on its end to an attachment (figure 6.5), elevated to the existing house height, the attachment is fixed to rafter strengthening s as detailed in the previous section. Beam to s are positioned at either side of the gable opening at the spacing determined in Section Gable Frame Assembly.

FIXING THE PANELS There are two types of profiles in the Cooldek range; Cooldek Classic and Cooldek CGI, refer figure below. The same procedure is used when fixing either option to the frame. COOLDEK CLASSIC for Classic and every second crest for CGI into the capping (and the flashing). If using 50mm Classic panels use 14x125mm hex head self drilling screws (14 x 150mm for 75mm Classic panels, 14 x 110 for 50mm CGI panels and 14 x 125 for 75mm CGI panels) refer figure 20.3. COOLDEK CGI When attaching the Cooldek Sheeting, start from the rear on one side of the gable. Lift the first sheet into place and slide firmly into the angled back channel. Check the sheet is square against the receiving channel and the capping and fix into position. Lay the next sheet of decking over the previous sheets side lap and ensure that the slip joint of the two sheets has engaged, refer figure 20.0 and 20.1. Note: The minimum Cooldek sheet length is 2.0m. If your design requires sheets smaller than 2.0m they will be supplied at 2.0m and require cutting on site. Ridge End Sheeting is fastened to the angled back channel using 4.8mm sealed rivets to the underside of the sheeting at maximum 200mm centres and 12 x 20 hex head self drilling screws with neoprene washer from the top into each crest for the Classic profile and every third crest for CGI, refer figure 20.2. Beam Capping End - WITH A SIDE GUTTER If a side is being attached to the unit an Angled Cutback Flashing will need to be fixed to the ends of the sheeting. Cut back the foam and the bottom skin of the insulted deck to the capping, refer figure 20.3. Slide the angled cutback flashing between the capping and the sheeting. Rivet the cutback flashing to the top sheet at 1000mm centres and fix the decking through each crest Pre-drill the crests of the ribs to provide clean holes for the seating of neoprene washers. Use cyclone caps and neoprene washers for all crest fixing. Do not over tighten screws. Fix side laps with 12x20 hex head screws with neoprene washer at approximately 1000mm centres. Silicone to waterproof all rivets. Beam Capping End - WITHOUT A SIDE GUTTER If no side is being installed fix the decking through each crest for Classic and every second crest for CGI into the capping.

Gable infill panels are to be cut in triangle shapes to fit the end frame. Panels can be painted to the desired colour before installing. End struts are fixed mid-span of the header to a header at the base and an end strut plate at the ridge. Infill panels are fixed through the top groove of rafters and the lower groove of the header with 8x35mm self embedding self drillingt screws at 500mm centres. Panels are fixed to the end strut at the same spacings. Attach the header flashing to the underside of the header with 12x20 hex head screws to neatly finish the base of the infill panels.

When plumb, fill the post hole with approximately 150mm of concrete and use a shovel or pole to agitate the concrete to remove any air pockets. Repeat this process until the hole is full, continually checking the posts as you go. The concrete must have a slight slope that runs away from the column to ensure any water does not pool around the base (figure 25.0). Once the concrete is set remove any temporary bracing or props. Fixing onto Existing Concrete: External Footing If the columns are to be fixed to an existing concrete slab with an external footing plate, each plate must be fixed to the concrete. For a 68 Outback Column refer figure 25.1, for a reinforced 68 Outback column refer 25.3 and for an SHS column refer figure 25.2. The minimum distances from an anchor hole to the concrete edge is 70mm for M10 anchors, 75mm for M12 anchors and 120mm for M16 anchors.
Fixing onto Existing Concrete: Internal Footing Ensure the M12 bolt is tightened. Refer figure 25.4 CONTACT 1300 165 165 Important Note Do not allow soil to remain in permanent contact with the columns, as corrosion will result in the base of the column. Refer to the Selection, Use and Maintenance of Stratco Steel Products brochure for complete details of the maintenance requirements. Downpipes Before attaching the downpipes, rivet the downpipe s to the column and bend the flanges along the break-line to accept the downpipe. Slide the downpipe over the outlet and rivet into position. Rivet the downpipe to the s.

Regular maintenance is essential to maintain the good looks of all Stratco steel products and to ensure you receive the maximum life-span possible. Washing with clean water must be frequent enough to prevent the accumulation of dust, salts, and pollutants that may reduce the life of the product. Stratco steel products that are regularly washed by rain require no additional maintenance. No Stratco steel structure or materials are recommended for use over, or in close proximity, to swimming pools or spas. No material that retains water (such as dirt or paving sand) should be placed against the columns. Care must be taken when determining the location of Stratco steel products so that they are not placed in close contact with sources of pollution or environmental factors that could affect the life of the steel.
